TULSA, Okla. (KTUL) -- Tulsa Public Schools says the district dropped three points in reading and math proficiency last year but says it's not an unexpected decrease.

The district announced its results Wednesday for the 2017-2018 Oklahoma State Testing Program. TPS says their results matched the decrease in state-level results, which they anticipated as students are working on more challenging state standards.

TPS says school-level results tend to fall below state averages, but the district did see double-digit growth at the Dual Language Academy, Mayo Demonstration, Project Accept, Jones Elementary and site 265, which was previously known as Lee Elementary. TPS had 31 school sites with increases in students with science proficiency, but cross most grade levels math proficiency remains lower than in reading.

“We have a lot of work to do to ensure that our students are well-prepared for life after high school,” said Superintendent Deborah A. Gist. “We are doubling-down on building strong academic foundations in the elementary grades with a relentless focus on literacy and numeracy, and we have seen some early successes with the use of instructional materials aligned to Oklahoma’s rigorous state standards.”

TPS plans to report on 2017-2018 performance and progress in mid-September.
